Police say they found several disturbing files on his laptop, including photos of children, mostly girls, ranging from 5-to-14 years old.

Smith has been charged with possession of child pornography. He was also ordered to stay off the Internet, unless it’s for business purposes.

Smith is a divorced father of two young children. He is a professor of material science and engineering and an adjunct professor of chemical engineering at the University of Utah.

Prosecutors say his laptop was purchased with grant money.

Smith does not have a criminal record, but prosecutors said Monday he admitted to police that he has traded pictures of teens over the Internet.

State police spokesman David Procopio issued this blistering statement about the arrest Sunday.

In the view of the State Police, child pornography is a form of child sexual abuse–nothing less. Those who possess it — a crime unto itself — foster an evil network that sexually abuses and exploits children irreparably.

Stopping child pornographers is a critical part of our mission to protect children. Along with our federal and local partners, we execute dozens of warrants related to this wicked crime each year. One hopes there is a special place in Hell for the evil people who make, trade, and possess child pornography. Until they get there, we are committed to putting them in jail.
